I have smoked and dipped over the years and I really don't think dipping would effect the deer at all. Heck cope tastes like dirt anyway so I wouldn't be surprised if the deer walked up and asked for a pinch. On the otherhand I can't imagine smoking while on stand is too good. I know during rifle season some of my friends smoke but they are on powerlines and the deer are pretty far away. The only time I ever saw a deer while smelling like smoke was a few years back. We were sitting at camp and I was in my hunting gear (done for the weekend) and I was smoking away. My friend talked me into going out one last time. We got into the woods and I didn't even feel like climbing a tree so I strapped on my stand and sat in it at the bottom, heck I could even smell myself. No more than an hour later a doe and her fawn walked up to me within 10 yards and never knew I was there. In retrospect I think wind played a huge role. This may be why some people see deer while smoking and others don't. If you play the wind right deer have a hard time smelling anything. IMHO.
